The IA-32 Execution Layer (IA-32 EL) is a software emulator in the form of a software driver that improves performance of 32-bit applications running on 64-bit Intel Itanium-based systems, particularly those running Linux and Windows Server 2003 (it is included in Windows 2003 SP1 and later[1] and in most Linux distributions for Itanium). The IA-32 EL bypasses the slow x86 hardware emulation which is available on pre-Montecito Itanium models.
Part of the software is under the LGPL and part is under an Intel proprietary license.[2]
